SUBSTITUTE FOR CORK.

SPECIFICATION forming part of letters Patent No. 395,241, dated December 25, 1888.

Application filed July 20, 1888. Serial No. 280,541. (No specimens.) Patented in Germany February 20, 1887, No. 40,643, and December 1, 1887, No. 43,906.

10 1887,) of which the following is aspcification.

The object of this invention is to produce from the )ith of the stalks of maize and other similarp an s a su s ance o ow specific gravity suitable for use as a substitutefor cork.

I 5 I prepare the new substance in the follow ing manner: About thzmhloaof ganulated ith (granulated to the size of a out t rec millimeters per granule) are intimately mixed in the presence of intense hegt with hot paste '20 or adhesive material. A s e paste is prepared by mixing about three kilos of starch with about twenty-seven mixture of pit'find-adh1ve material is placed in molds and immediately dried by ex- 2 5 posing the mixture to a temperat to made, on account of its very low specific gravity, non-conductibility of heat, and en'- treme cheapness, as the material from which this new cork-like mass is produced could heretoforebe used only for fuel. The above- 3 5 mentioned proportions have proved to be the best in practice; but they may be varied without departing from the invention. 1 a

The prepared mass may be introduced into commerce in the form of molded blocks or 0 pieces or be ground to powder or granulated or prepared according to its intended use."

-scribing witnesses.

The above-named starch-paste used for producing thenew mass may be replaced by any other suitable adhesive material.

This cork-like substance is easily made elastic by adding-thereto before molding a certain quantity of linseed-oil or tar. The mass will then remain elastic even after drying.

In addition to these numerous advantages the mass can also be made fire-proof by adding to the mixture of pith and paste before drying a fireproofing substance-such as wateri ss or m1 l e of soda dissolved in a suiiaiiie solvenl suc 1 as wa eror a fireproof mineralsuch as infusor it clav or the like." The rle' mass is t en coinp e e y fire proot', and may be used in various manners, owing to its low specific gravity.

Having now particularly described the nature of the said invention and in what manits.

ner the same is to beca-rried out, I declare that what I claim isstitute for cork, consisting of powdered pith of stalks-such as maize-stalks-an adhesive material-'-such as starch-paste-and a substance-such as lin seed-oilto render the mass elastic, substantially as described.
